This study evaluates the effect of GnRH agonist (GnRHa) trigger for ovulation induction among women with advanced maternal age (AMA). This is a retrospective study performed at a single assisted reproductive technology centre, 2012 to 2020. A total of 306 patients with 515 IVF cycles who were triggered with GnRHa for Ovum Pick Up (OPU), were divided into two groups according to maternal age: age ≥ 40 and age < 40. The groups were compared for demographics, stimulation parameters of IVF treatment and IVF treatment outcomes. The patients in the age < 40 group were approximately 10 years younger than the patients in the age ≥ 40 group (31 ± 5.4 vs. 41.5 ± 1.3 years, p < 0.001). The age ≥ 40 group had significantly higher mean E2/retrieved oocytes ratio, compared to the age < 40 group (310.3 ± 200.6 pg/ml vs. 239 ± 168.2 pg/ml, p = 0.003), and a lower mean MII/retrieved oocyte (35 ± 37.8 vs. 43.4 ± 35.9, p = 0.05, respectively). Multivariable logistic regression analysis for E2/retrieved oocytes demonstrated that age < 40 and total dose of gonadotropins were significant variables. In conclusion, GnRHa for ovulation triggering in high responder patients prior to OPU appears to be a good option for AMA. However, this population is characterized by different parameters of ovarian response that require further evaluation.
